Integers & Order of Operations Help Fun Game Tips:
- Adding positive and negative integers can be compared to winning and losing money.
- A win of $4 added to a loss of $6 results in a total loss of $2. That is (+4)+(-6)=(-2).
- To subtract an integer, you can add its opposite.
- That means (-3)-(+7) is the same as (-3)+(-7) = -10.
- Also (6)-(-2) is the same as (+6)+(+2)=8, because removing a $2 loss gives a $2 gain.
- When multiplying 2 integers having the same sign, the result is positive. Example (-4)(-5)= 20.
- When multiplying 2 integers having different sign, the result is negative. Example (-3)(+6)= -18.
- The positive and negative sign rules for integer division are the same as for integer multiplication.
- The order of operations requires that bracket operations be done before the 4 basic operations.
- As a general rule, when several of the 4 basic operations occur in succession,
do multiplication and division first (from left to right)
followed by addition and subtraction (from left to right).
